4 choices:
If you don't want to run a servo to change polarity, AND you want both C- and Ku- on one dish, there are few choices:
- very expensive orthomode feedhorn and two C-band, plus two Ku band LNBs!

- BSC-621. it's gotten a bad reputation over the years. may just need TLC
- DMX741. new kid on the block. currently in test by some users
- CK-1. seems well proven by dedicated tuners.
If you read through the threads, you'll get the idea that a few users are happy with their BSC 621's.
They're certainly fine for c-band. Most had serious trouble getting Ku to work.
Was it the equipment... or the testers....? Who knows?
Linuxman may be super careful at tuning, but has gotten good results from the Ck-1 on Ku band.
Seeing the potential, others have found it to work pretty well, even if tune up seemed challenging.
If you need to order something now, this is a good working solution.
I made my decision to get one last year, and felt it was the right move.
If you have a month to wait for test results, the DMX741 will be discussed more on the forum.
They're really not too expensive, so you could try one now if you like, and be a tester, too.
